Major vulnerability found in WPA2 protected networks.

Dr Vanhoef, a researcher at KU Leuven, published the details of what he branded the KRACK (key reinstallation attack) on Monday.
Experts claim it poses a huge risk to businesses - and warn the issue may never be completely fixed for old phones and routers

Sorry but isn't this only information not sent via HTTPS etc. over Wi-Fi

How often do you look to check if the padlock is there ??? I know I often forget to check.

Websites aren't the only use of LAN/WLAN's. Access a LAN, then you can try and attack weak devices and extract admin credentials which may be reused on other devices for example. Lets just say your credit card company for example has security for their website, but anyone could just sit outside the office and sniff data......

Now that any script kiddie can download this, the risk of attack becomes much less than just hypothetically possible.

Re: Major vulnerability found in WPA2 protected networks.

I'm guessing you mean say I was hardwired, this attack won't work.

However lets say consider a typical office with LAN+WLAN all on the same broadcast domain and VLAN. Even if all devices intended to be connected are hardwired, someone can still connect to the LAN via WLAN, then start exploiting weak devices and hopefully find the admin credentials on a weak device are the same on many other devices.
